Maschinenfabrik Aktiengesellschaft, Chemnitz, Germany 'Application December 11, 1934, Serial No. 757,048 I In Germany December 14, 1933 z claims. (cl. cis-isa) The present invention rrelates to a method of widening fabrics on flat knitting machines, i. e. a

method *of widening particularly required for the manufacture of the heels of stockings.

Hitherto the widening of such fabrics was effected either by forming new loop wales by casting on of loops, or by transferring of loops, known as widening, for instance by transferring of loops .to be sewn in the marginpor'els'e the thread guide wasr after finishing of a row of loops, moved for thev pitch of two needles beyond the margin of the fabric and the thread, passing around the outer needle in a manner known for selvedge needles,-

was placed in front of all the needles for forming a new row of loops, whereupon during the formation of the next row of loops either the last but one added selvedge needle or the last seivedge needle was not pressed and thereby received a tuck loop, whereafter further rows of loops folv 2olowed.

Besides the disadvantage of the first mentioned method which requires rather complicated special devices and the draw-back of the second mentioned method which causes loop distortions, the fabric was enlarged or widened for two loop wales only withall these methods.

The method of widening fabrics according to the present invention allows the enlargement or widening of the fabric for the pitch of four needles without requiring further special structure. This l is offspecial importance in the manufacture of stockingsin a single operation having a bending corresponding to a humans foot, as then the outer widening results quickenough with regard to the bending. V

In the accompanying` drawings Figs. 1`6 are diagrams showing the successive steps of enlarg- .ing or widening of the fabric according to the method of the invention, and Fig. '7 shows a piece -40 of fabric widened 'or enlarged in' accordance with the method of the invention.

Afterthe formation of the'usual rows of loops a and b on the needles li to 28 the thread guide, coming from the right-hand side'of row c and standing outside the needle Il, outwardly passes around two needles III and 9 as shown in Fig. 1. The thread is, in a manner known for selvedge needles, taken about the needle 9 and is then further placed in front of all needles from I0 to 28 for forming the row o f loops d.

Upon the finishing of this row of loops d, the thread guide is in the same manner outwardly moved at the other side, i. e. at the right hand side, for thepitch of two need1es,'needles 29 and 30, the thread being laid around the needle 38 and lthen further placed in front of all the needles 29 to9 and sunk. v i

The'foregoing operation for knitting fabric. is set forth in my Patent No. 1,955,632, dated April 17, 1934 as is also the step in'` the method that at ."5 'the formation of thenext row of loops the last but one added selvedge needle i8 is not pressed.

The novel feature ofthe present methodaccording to the invention is the step that, when the thread guide at the right hand side is passed out- 10 wardly around the needles 29 and 38, at the same time the thread guide stop at the left hand side is moved outwardly' for the pitch of two needles, i. e. the needles 8 and 1, so that the thread, as shown in Fig. 3, is not only placed in front of the needles 1 29 to 9, but alsoplaced in front of the needles 8 and 1 and sunk, whereby the row e is enlarged or widened for the pitch of four needles.

After the formation of this row of loops the thread guide is, in a manner known per se, moved 20 youtwardly around the needles 8 and 5 and simultaneously the thread guide stop at the opposite side of the fabric is, according to` the invention, moved outwardly for the pitch of two needles,

i. e. the needles 3| and 3,2, so that the thread 25 after having been taken about 'the needle 5, is placed in front of all the needles 8 to 32 and sunk, whereby the row f is widened or enlarged for the pitch of four needles. During the formation of v this row of loops, the last but one -of the previ-^ 30 usly added selvedge needles, l. e. the needle 29 I at the right hand side, and the third last and last added selvedge needles, i. e. the needles 9 and 'l at the left hand side, are not pressed, so that, as

shown in Fig. 4, the needles 1, 9 and 29 receive 35 tuck loops. ,o From the foregoing, it is obvious that a tuck loop is formed upon the needle 1and the loop thereon is not knocked over into the row-of loops ve, the noose or loop formed between needles 8 and 40 1 cannot engage or hang itself into a loop of the preceding rowof loops e, with theresult, that the thread between needles 5 and 6 Vas well as between needles .8 and 1 is againstretched.

The described operation is repeated in the same 45 manner since now, after the formation of the row of loops f, the thread guide at the right hand side passes outwardly around the needles 33 and 3l while simultaneously the thread guide stop at the opposite side is moved outwardly for the pitch of 50 the needles l and 3, so that the thread, after having been taken about the needle 34, is placed in front of the needles from 33 to 3 and sunk. Herey by the row g is enlarged or widened for the pitch of four-needles and at the left hand side the 55 f 2 previously addedlut but one selvedge. needle e,

` -thefourth last selvedze needle I and the sixth Vlast selvedze needle Il and at the right hand side the added last selvedge needle l last' selvedse needle lo are noi:

32 and the third so that. as l, I0, yIl and I2 shown in Fig. 5, the needles t,

I recelve'tuck loops.

i, As

inner loop vupon last selvedireneedle l{lilieoperation* is further since now\ the formation of this row of loops the duide mit the left hand side is passed outwardly around the needles 2 and l and simultane-l ously at the ritht hand side the thread luide stop is moved outwardly for the pitch. of the needles Il and It, so that in this manner now the row h is enlarged orv widened foxl the pitch of four needles, after needle 2l at the ritht hand side and the addedl 8, the third last selvedse needle I andthe'tlfth last selvedseneedle ,1 at are not pressed, whereby, as shown in Fig. 6, the needles I. I, 1, Il, li and 83 receive tuck loops. y

may be seen from Fig. 7, always each second each loop wale is formed as a tuck loop, so that the formation of two-needle 11111811111! this row, the previously v l added last. but one selvedge needle u. the fourth i last'kselvedze needle lli and the sixth last selvedxe wales is prevented, as at least one tuck loop is present in each loop wale -of the newly formed pairvof loops. l
